At 800 AM CST...A powerful low pressure system was centered just
to the north of Lake Superior in southern Canada and expected to
continue racing northeast, away from the United States. An
associated cold front was observed extending through the Midwest
and into the Southern Plains, while a warm front extended east
into northern New England. A tight pressure gradient stemming from
the strong low pressure system has produced the threat for high
winds across Upper Great Lakes. Current RADAR and surface
observations indicate light to moderate snow falling across parts
of Minnesota and far northern Wisconsin.
...Selected preliminary Peak Wind gusts in miles per hour earlier
in the event...

As the low pressure system continues to push away from the Lower
48, light snow will continue across parts of the Upper Great
Lakes. A few additional inches of snowfall is expected throughout
northern Minnesota, northern Wisconsin, and the U.P. of Michigan.
Gusty winds may produce reduced visibility across localized
regions where snow continues. Potentially damaging wind gusts up
to 60 mph are also expected to linger into the afternoon for parts
of the Great Lakes, before winds diminish tonight. *Cities noted
with an asterisk indicate wind gusts that were observed in
thunderstorms.
This will be the last Storm Summary issued by the Weather
Prediction Center for this event. Please refer to your local
National Weather service office for additional information.
